Since you can send faxes using documents stored in the printer, you can save the time spent scanning documents when you need to send the same document frequently. You can store up to 100 pages of a single document in monochrome. You can store 10 documents in the printer's stored documents box.
Saving 10 documents may not be possible depending on the usage conditions such as the file size of stored documents.
Place the originals.
Select Fax Box on the home screen.
Select Stored Documents, tap 
(Box Menu), and then select Store Fax Data.
In the Fax Settings tab that is displayed, make settings such as the resolution as necessary.
Tap 
to store the document.
After storing a document is complete, you can preview the scanned image by selecting Fax Box > Stored Documents and then tapping the box for the document, or you can delete it by tapping 
on the right of the box for the document.
